Congrats to you and your lo. It is a big adjustment and I had jsut as many questions as you when I first had Owen. But you are lucky, because you have found this site very early on. I wish I had.
First off, if you suspect reflux, discuss it with your dr ASAP. The sooner it is diagnosed, the better. My lo had it and I didn't know that that's what it was until it had passed. Poor little guy.
I would also suggest holding off on the pumping for a little bit. The first month is extra hard on the mama, but it is only one month, it will past sooooo fast, trust me.
I would suggest another tactic if your lo falls asleep at the breast. Try breast compression to kepe your milk flowing. The lo will likely nurse even if they are sleeping. Feed him in his sack if you like, there is nothing wrong with that. But our trick to keep our lo awake during night feeds so that his tummy was full, was to change his nappy midfeed.
Your los A time should consist pretty much of just a nappy change. They sleep, cry and eat almost all the time at that age.
If you suspect gas, perhaps try some gripe water.
My lo would never take a dummy at that age.
And to echo what the last poster said. Don't stress EASY so much at that age, especially if the feeds are being spit up and you feel you need to nurse again. Do what makes you feel best, because you are mama and know best. But remember, if they held it down for a bit, they have already absorbed all the nutrients that they need.
It sounds like you are doing relaly well. Hang in there... everyone gets the "mommy blues". Things will start looking up, I found it really true around the 5 - 6 week mark.
